Description

  The present invention relates to a self-luminous display board having a backlight used for, for example, a camera mode dial and a speedometer, and a display device having the same, and in particular, a three-dimensional display with a thickness on a flat display. The present invention relates to a display plate, a display device, an electronic device, and a measurement device that can give a feeling of feeling and floating, and can make the appearance of the entire display plate different between illuminated and non-illuminated.

  Some single-lens reflex cameras and compact cameras have a mode dial for selecting one of a plurality of program exposure modes. A conventional mode dial has a configuration in which a figure, a symbol, a character, or a number displayed on a rotatable circular dial is matched with an index position fixed to the camera body.

  Further, Patent Documents 1 to 7 below propose a mode dial in which a display of a pictograph or the like having translucency is formed on the dial and the display is illuminated by an LED backlight. In such a mode dial with illumination, when the dial is rotated and the display of pictograms or the like is adjusted to the index position, the display is self-luminous to notify the selected mode.

JP 2001-005075 A JP 2001-005076 A JP 2001-005085 A JP 2002-062570 A Japanese Patent Laid-Open No. 2002-075106 JP 2006-003806 A JP 2007-199362 A

  However, the mode dials of Patent Documents 1 to 7 have a problem in that the display is flat and lacks novelty because the display of pictograms and the like having translucency is merely made to emit light by the LED backlight. . Further, the display of translucent pictograms or the like is generally milky white or translucent, and there is a problem that the visibility when not illuminated is lower than that of a light-shielding printed display.

  Furthermore, the mode dials of Patent Documents 1 to 7 are all different in whether or not any display is lit when illuminated and when not illuminated, and the appearance of the entire display unit is illuminated and not illuminated. It did not make a big difference with time.

  Some automotive instrument panels have a blackout type that does not show the meter display except when the self-luminous meter cover is covered with smoke glass with a transmittance of about 20% and the ignition key is turned on. It was. In such a blackout type self-luminous meter, when the ignition key is turned on, the display of the meter appears, and the appearance of the entire display board is greatly different between illuminated and non-illuminated.

  However, the blackout-type self-luminous meter cannot be used without seeing the meter display unless the backlight is always turned on, and cannot be used with the backlight turned off on a sunny day. There's a problem. Also, in order to black out the entire display board when the backlight is turned off, the design of the display board is limited to dark (generally black), and a fine design such as a texture pattern is applied to the surface of the display board. However, there is also a problem that it is too dark to be visually recognized.

  The present invention has been made in view of the above problems, and can provide a three-dimensional effect and a floating feeling by giving thickness to a flat display, and the appearance of the entire display panel can be illuminated and non-illuminated. It is an object of the present invention to provide a display panel, a display device, an electronic device, and a measurement device that can be made different.

  In order to achieve the above object, a display panel of the present invention is a display panel that illuminates a static display formed on a substrate with a backlight, the substrate made of a light-transmitting material, and the substrate A light-shielding positive display located on the front surface side, a light-shielding layer located on the back side of the substrate, and a contour formed in the light-shielding layer, corresponding to the positive display, and having a thickness of the substrate The positive display and the negative display are overlapped with each other, the sizes of the positive display and the negative display are made different from each other, and the respective contour shapes are offset.

  According to the above configuration, the positive display and the negative display in which the contour shapes are offset from each other are overlapped at an interval in the substrate thickness direction so that the light-shielding positive display can be obtained when the backlight is illuminated. It is illuminated from behind with the illumination that has passed through the display, and the integrated display formed by the positive display and the negative display can be viewed three-dimensionally. On the other hand, when the backlight is not illuminated, the light-shielding positive display can be viewed well by receiving light from the outside.

  Preferably, the positive display and / or the negative display is formed by printing, more preferably, the positive display and / or the negative display is printed on a film, and the film is stacked on the substrate. Good.

  According to the above configuration, when the positive display and the negative display are directly printed on the substrate, the laminated structure of the display plate can be simplified, and the display plate can be thinned and the number of assembly steps can be reduced. On the other hand, when a positive display or negative display is printed on a film and laminated on a substrate, the film can be colored or textured, and the background of the display board can be designed arbitrarily. Become. Preferably, when a positive display and a negative display are printed on the back surface of the film, the positive display and the negative display are protected by the film.

  Preferably, the light shielding layer has a configuration in which black printing excluding the negative display is performed, and more preferably, a semi-transparent background decoration layer is formed above the light shielding layer on the back surface side of the substrate. It is good also as the structure which carried out.

  According to the said structure, the light-shielding property of the background part except a negative display can be made favorable by making a light shielding layer black printing. In addition, a semi-transparent background decorative layer is formed above such a light shielding layer, and the negative display is covered by this background decorative layer, so that the negative display is concealed when the backlight is not illuminated. It becomes possible to unify the background design of the display.

  Preferably, a light-blocking, light-transmitting or semi-light-transmitting background decorating layer having a light-transmitting property at least in a region corresponding to the negative display above the light-blocking layer on the back surface side of the substrate. Preferably, a semi-transparent background decoration layer corresponding to at least the negative display may be formed below the light-shielding layer on the back side of the substrate.

  According to the above configuration, the background decorative layer is light-shielding or semi-transparent while ensuring the amount of light that passes through the negative display by providing translucency to at least the region corresponding to the negative display of the background decorative layer. It can be any of light, and the degree of freedom in the background design of the positive display can be expanded. In addition, by forming at least another semi-transparent background decoration layer corresponding to negative display below the light shielding layer, only the negative display can be designed differently from the background portion.

  Preferably, the background decoration layer may be any one of a metal thin film, color printing, smoke printing, or texture pattern printing composed of fine unevenness.

  According to the said structure, the background or negative display of a display board can be made into various designs by the metal thin film, color printing, smoke printing, or any one or combination of 2 or more of fine unevenness | corrugations.

  For example, when the background decoration layer is formed of a metal thin film, the background of the display board or the appearance of the negative display can be made into a metal tone, a mirror tone, a shell tone, or the like. Since the background decoration layer is formed on the substrate separately from the light shielding layer, the metal film as the background decoration layer may be either light shielding or translucent.

  Moreover, when the background decoration layer is color-printed, the background or negative display of a display board can be colored in arbitrary colors. The color of color printing may be chromatic or achromatic, and may be one color or two or more colors. Color printing may be performed on the metal thin film described above, and the background decoration layer may be a metallic color.

  In addition, when the background decoration layer is smoke-printed, for example, the background design of the positive display is concealed when the backlight is not illuminated by smoke-printing both the background of the display board and the negative display. Can be unified. Alternatively, only the negative display may be smoke printed to make it black.

  In addition to this, when the background decoration layer has fine irregularities, a texture pattern that gives a texture to the background or negative display of the display board can be added. The fine irregularities include all kinds of patterns such as a metal-processed hairline pattern, a carbon fiber fiber pattern, a general checkered pattern, a polka dot pattern, and an arabesque pattern.

  Preferably, an illumination coloring layer for coloring illumination of the backlight is formed below the light shielding layer on the back side of the substrate. According to such a configuration, the illuminated colored layer can emit the background or negative display of the display panel to an arbitrary color when the backlight is illuminated, and the degree of freedom in design during illumination can be expanded. it can.

  Preferably, it is good also as a structure which laminated | stacked the translucent decorating film which formed the texture pattern which consists of fine unevenness | corrugation on the surface side or back surface side of the said board | substrate. According to such a configuration, for example, when the decorative film is laminated on the surface side of the substrate, the texture pattern can be added to the entire display board including the positive display. In addition, when the decorative film is laminated on the back side of the substrate above the light shielding layer, a texture pattern can be added to the background of the display board and the entire negative display, and laminated below the light shielding layer. In this case, the texture pattern can be expressed only in the negative display when the backlight is illuminated.

  The above-described display board of the present invention includes, for example, an operation unit of an electronic device such as a mode dial of a camera, a dial of a measuring device such as a speedometer, a tachometer, and a clock, a nameplate for displaying a company name and a store name, and a personal nameplate It is possible to apply widely.

  As described above, according to the display board of the present invention, and the display device, electronic apparatus, and measuring device provided with the display plate, a three-dimensional effect and a floating feeling can be given by giving thickness to a flat display, and a display The overall appearance of the plate can be made different between illuminated and non-illuminated.

[First Embodiment]
Hereinafter, the display panel according to the first embodiment of the present invention will be described with reference to FIGS.

<Overall configuration>
1A and 1B show the appearance of the display panel 1 according to the present embodiment when not illuminated. In these drawings, the display board 1 displays a light-shielding positive display 10a (see black “ABC” in the figure) printed on the surface of a transparent substrate 10 by a backlight such as an LED (not shown). It is configured to illuminate from the back side.

  As shown in the cross-sectional view of FIG. 1C, a light shielding layer 11 colored in an arbitrary color is printed on the entire back surface of the substrate 10. In this embodiment, since the light shielding layer 11 is printed directly on the back surface of the transparent substrate 10, the color of the light shielding layer 11 becomes the background color of the display panel 1. The light-shielding layer 11 is preferably a dark color with high light-shielding properties such as black, dark blue, and dark brown (in FIGS. 1A to 1C, the color of the light-shielding layer 11 is indicated by hatching for convenience of illustration). . When the background of the display panel 1 is a light-colored, semi-transparent metal film or smoke printing having a low light-shielding property, a background decoration layer separately from the light-shielding layer 11 as shown in FIG. 21 may be provided.

  In such a light shielding layer 11, a translucent negative display 11a is cut out and printed. The negative display 11 a has a contour shape corresponding to the positive display 10 a and overlaps with the positive display 10 a through the thickness of the substrate 10. In this embodiment, the width L2 of each part of the negative display 11a is made slightly larger than the width L1 of each part of the positive display 10a, and the contour shape of the negative display 11a is changed as shown in FIGS. 1 (a) and (b). The offset is offset to the outside of the contour shape of the positive display 10a.

  Returning to FIG. 1C, under the light shielding layer 11 on the back surface side of the substrate 10, a translucent illuminated colored layer 12 colored in an arbitrary color is printed. The illumination coloring layer 12 is interposed between the negative display 11a and the backlight, and colors the illumination transmitted through the negative display 11a into an arbitrary color.

<Appearance of display panel when not illuminated>
As shown in the left diagrams of FIGS. 1A and 1B, when the backlight is not illuminated, the display panel 1 receives light from the outside and exhibits a color and texture as designed. For example, if the positive display 10 a is red and the light shielding layer 11 is black, a red planar “ABC” character appears on the black background through the thickness of the substrate 10.

  At this time, the negative display 11a exhibits the color of the illumination colored layer 12 itself. For example, when the color of the illumination colored layer 12 itself is the same color (for example, black) as that of the light shielding layer 11, the negative display 11a can be made inconspicuous at the time of non-illumination. On the contrary, when the color of the illumination colored layer 12 itself is set to the opposite color (for example, white) of the light shielding layer 11, the negative display 11a can be conspicuous at the time of non-illumination. In this case, if the color of the illumination colored layer 12 itself is different from the color of the positive display 10a, the periphery of the positive display 10a is bordered by the negative display 11a when viewed from the front under the light from the outside. appear.

<Appearance of display panel during illumination>
1A and 1B show the appearance of the display panel 1 according to the present embodiment when illuminated. In these drawings, the illumination from the backlight is colored by the illumination coloring layer 12, passes through the negative display 11a, and illuminates the positive display 10a from behind. Then, the positive display 10a and the negative display 11a are integrated to form one three-dimensional display. In other words, the positive display 10a that receives light from the rear surface appears in the light transmitted through the negative display 11a. The positive display 10a is the upper surface of the three-dimensional display, the negative display 11a is the lower surface of the three-dimensional display, and the substrate 10 Of these, the portion through which the illumination is transmitted forms a three-dimensional display thickness. As a result, in the display board 1 of the present embodiment, it appears that the three-dimensional display of “A”, “B”, and “C” having the thickness of illumination is individually present in the transparent substrate 10.

<Effect>
According to the display panel 1 according to the present embodiment, a three-dimensional effect and a floating feeling can be given to the planar positive display 10a with a thickness. In particular, when the backlight is not illuminated, the entire display panel 1 can be displayed with the color and texture as designed under the light from the outside, and the negative display 11a is transmitted in the dark where there is little light from the outside. The three-dimensional display in which the positive display 10a appears in the illuminated light can be formed, and the appearance of the entire display panel 1 can be greatly different between when illuminated and when not illuminated.

<Example of change>
In the present embodiment, the width L2 of each part of the negative display 11a is slightly larger than the width L1 of each part of the positive display 10a, and the contour shape of the negative display 11a is offset to the outside of the contour shape of the positive display 10a. The display board of the present invention is not limited to this configuration. As shown in FIG. 1D, the width L2 of each part of the negative display 11a is made slightly smaller than the width L1 of each part of the positive display 10a, and the contour shape of the negative display 11a is set to the inside of the contour shape of the positive display 10a. It is good also as a structure offset to.

[Second Embodiment]
Next, a display panel according to a second embodiment of the present invention will be described with reference to FIGS. In these drawings, the display panel 2 of the present embodiment has a configuration in which a semi-transparent background decoration layer 21 is formed above the light shielding layer 11 on the back side of the transparent substrate 10.

<Overall configuration>
FIGS. 2A and 2B show the appearance of two types of display panels 2 and 2 with different background decoration layers 21 when not illuminated. The display board 2 in FIG. 5A includes a metallic background decoration layer 21A, and the display board 2 in FIG. 5B includes a smoke background decoration layer 21B.

  As shown in FIG. 2E, each of the display plates 2 and 2 has a configuration in which a thin transparent film 20 is laminated on the surface of the substrate 10. On the back surface of the film 20, a light-shielding positive display 20a (see black coating “ABC” in the figure) is printed. On the other hand, a background decoration layer 21 is formed on the back surface of the substrate 10, and the light shielding layer 11 is printed under the background decoration layer 21.

  The film 20 only needs to have resistance according to the use of the display panel 2, and may be, for example, PET (Polyethylene Terephthalate), polycarbonate, silicone, or the like. Moreover, when applying the display board 2 to the operation part of an electronic device, a nameplate exposed to the exterior over time, etc., it is preferable to give the surface of the film 20 a hard coat for preventing scratches.

  The background decoration layer 21 constitutes the background design of the positive display 20a on the display board 2. For example, a metal thin film can be deposited on the back surface of the substrate 10 by half sputtering of Al or SUS to form a metallic background decoration layer 21A. Moreover, a semi-transparent smoke color (black semi-transparent) can be printed on the back surface of the substrate 10 to obtain a smoke-like background decoration layer 21B. Further, a semi-transparent color other than black may be printed to form the background decoration layer 21C of any color.

  On the light shielding layer 11, a negative display 11a similar to that of the first embodiment is printed out. In this embodiment, since the light shielding layer 11 is printed under the background decoration layer 21, the negative display 11 a is covered with the background decoration layer 21 when viewed from the front surface side of the display panel 2. Thereby, the outline shape of the negative display 11a can be made invisible when the backlight is not illuminated.

  Others are the same as in the first embodiment, and the negative display 11a has a contour shape corresponding to the positive display 20a and overlaps with the positive display 20a through the thickness of the substrate 10. The width of each part of the negative display 11a (see L2 in FIG. 1C) is slightly larger than the width of each part of the positive display 20a (see L1 in FIG. 1C). As shown in (b), the contour shape of the negative display 11a is offset to the outside of the contour shape of the positive display 20a.

<Appearance of display panel when not illuminated>
2 (a) and 2 (c), the display board 2 that employs the metallic background decoration layer 21A exhibits a smooth appearance without unevenness of the positive display 20a on the surface by the film 20. The background decoration layer 21 </ b> A forms a mirror-finished background through the thickness of the transparent substrate 10. When the backlight is not illuminated, the outline shape of the negative display 11a is not visible, so the background is mirror-finished with no line drawings or patterns. On such a mirror-finished background, the letters “ABC” (for example, red) on the flat positive display 20a appear to float. Furthermore, the letters “ABC” appear in the mirror-finished background, and a pair of “ABC” of the real image and the virtual image appears as a planar double image through the thickness of the substrate 10.

  On the other hand, in the upper diagrams in FIGS. 2B and 2D, the display panel 2 adopting the smoke-like background decoration layer 21 </ b> B has the background decoration layer 21 </ b> B through the thickness of the transparent substrate 10. Forming a glossy black background. On such a black background, the letters “ABC” (for example, red) on the flat positive display 20a appear to float. In addition, like the metal-like background decoration layer 21A described above, the film 20 exhibits a smooth appearance without unevenness of the positive display 20a on the surface. Further, when the backlight is not illuminated, the outline shape of the negative display 11a is not visible, so that the background is unified to a black background without any diagram or pattern.

<Appearance of display panel during illumination>
2C and 2D, the illumination from the backlight passes through the negative display 11a and the background decoration layer 21A or 21B, and illuminates the positive display 20a from behind. Then, as in the first embodiment, the positive display 20a and the negative display 11a are integrated to form one three-dimensional display. As described above, the positive display 20a that is illuminated from behind appears in the illumination transmitted through the negative display 11a. The positive display 20a is the upper surface of the stereoscopic display, and the negative display 11a is the lower surface of the stereoscopic display. A portion of the substrate 10 through which illumination is transmitted forms a three-dimensional display thickness.

  As a result, in the display panel 2 employing the metallic background decoration layer 21A, the three-dimensional display of “A”, “B”, and “C” with the thickness of illumination is individually provided on the mirror-finished background. Seems to exist. On the other hand, in the display panel 2 adopting the smoked background decoration layer 21B, three-dimensional displays of “A”, “B”, and “C” having the thickness of illumination individually exist on the black background. Looks like to do.

<Effect>
According to the display board 2 which concerns on this embodiment, by forming the semi-transparent background decoration layer 21 above the light shielding layer 11, the background of the positive display 20a is made into a metallic tone, a mirror tone, a shell tone, Various designs with different colors and textures, such as smoke and color, can be made. Further, by covering the negative display 11a with the background decoration layer 21, it becomes possible to conceal the negative display 11a and unify the background design of the positive display 20a when the backlight is not illuminated.

  Further, when the backlight is not illuminated, the entire display panel 2 can be displayed with the color and texture as designed under the light from the outside, and the negative display 11a is transmitted in the dark where there is little light from the outside. The three-dimensional display in which the positive display 20a emerges in the illuminated light can be formed, and the overall appearance of the display panel 2 can be greatly different between when illuminated and when not illuminated.

[Third Embodiment]
Next, a display panel according to a third embodiment of the present invention will be described with reference to FIGS. 3 (a) and 3 (b). In these drawings, the display board 3 of the present embodiment has a configuration in which a background decoration layer 31 is printed on the back surface of a transparent substrate 10 and a light shielding layer 11 is printed under the background decoration layer 31. The background decorative layer 31 is printed with a similar negative display (translucent portion) 31a corresponding to the negative display 11a of the light shielding layer 11.

  As described above, the region corresponding to the negative display 11a of the background decoration layer 31 is provided with translucency, so that the background decoration layer 31 is light-shielding and transparent while ensuring the amount of light that passes through the negative display 11a. It can be made light-transmitting or semi-transmitting, and the degree of freedom of the background design of the positive display can be expanded.

  In addition, as the light-shielding or translucent background decorating layer 31, for example, the above-described metal film, smoke printing, and color printing are applicable, and as the translucent background decorating layer 31, for example, described later This corresponds to a textured pattern printing or decorative film made of fine irregularities.

[Fourth Embodiment]
Next, a display panel according to a fourth embodiment of the present invention will be described with reference to FIGS. 4 (a) to 4 (c) and FIGS. 5 (a) to 5 (c). In these drawings, the display panel 4 of the present embodiment has a configuration in which a decorative film 40 having translucency in which a texture pattern made of fine irregularities is formed is laminated on the front surface side or the back surface side of the substrate 10.

<Overall configuration>
FIGS. 4A and 4B show the appearances of the two types of display plates 4 and 4 having different texture patterns of the decorative film 40 when not illuminated and illuminated. The display board 4 in FIG. 5A includes a decorative film 40A on which a fiber pattern of carbon fiber is formed, and the display board 4 in FIG. 5B has a decorative film 40B on which a hairline pattern made of metal is formed. I have.

  As shown to Fig.5 (a)-(c), the decoration film 40 becomes the structure which formed the texture pattern which consists of fine unevenness in the surface or back surface of a transparent film, and the background decoration layer 21 mentioned above and Together, it exhibits an appearance simulating the texture of carbon fiber or surface-treated metal.

  Specifically, by stacking the smoke-like background decorating layer 21B under the decorating film 40A in which the fiber pattern of the carbon fiber is formed, an appearance in which black carbon fibers are knitted in a lattice shape is obtained. In addition, by laminating a metal-like background decoration layer 21A under the decorative film 40B on which a metal-processed hairline pattern is formed, the appearance of a dull metal surface with a fine linear pattern is obtained. .

  Here, the decorative film 40 may be laminated on either the front surface side or the back surface side of the transparent substrate 10. For example, as shown in FIG. 5A, the decorative film 40 is laminated on the surface of the substrate 10. In this case, the positive display 20 a is printed on the back surface of the decorative film 40. The texture pattern of the decorative film 40 may be formed on either the front surface or the back surface. When the texture pattern is formed on the surface of the decorative film 40, when the surface of the display board 4 is touched with a finger, the texture pattern can be felt by touch. Moreover, like the metal-worked hairline pattern shown in FIG. 4B, when it is desired to make the surface of the display board 4 have a dull appearance, a texture pattern may be formed on the surface of the decorative film 40. On the contrary, like the carbon fiber fiber pattern shown in FIG. 4A, when it is desired to give the surface of the display panel 4 gloss, a texture pattern may be formed on the back surface of the decorative film 40.

  Further, for example, as shown in FIG. 5B, a configuration may be adopted in which a decorative film 40 is laminated on the back surface of the substrate 10 and a background decorative layer 21 is printed thereunder. In this case, there is an advantage that the texture pattern of the decorative film 40 and the background decorative layer 21 can be seen integrally. When the decorative film 40 is laminated on the back surface of the substrate 10, the background of the carbon fiber tone or the metal hairline tone can be seen through the thickness of the transparent substrate 10. In particular, when the background is made of carbon fiber, the appearance of the display panel 4 can be made to closely resemble FRP (Fiber Reinforced Plastics) in which carbon fiber is put in plastic.

<Appearance of display panel when not illuminated>
As shown to the left figure of Fig.4 (a), in the display board 4 which employ | adopted the decoration film 40A which formed the fiber pattern of carbon fiber, this decoration film 40A and the smoked background decoration layer 21B and Together, they form a carbon fiber-like background. Since the light shielding layer 11 is printed under the background decoration layer 21B, the outline shape of the negative display 11a is concealed when the backlight is not illuminated, and the appearance of the background is unified to a black carbon fiber tone. On such a carbon fiber-like background, the letters “ABC” (for example, white) on the flat positive display 20a appear to float.

  On the other hand, as shown in the diagram on the right side of FIG. 4B, in the display board 4 that employs a decorative film 40B in which a metal-worked hairline pattern is formed, the decorative film 40B and a metallic background decorative layer are provided.

  As shown in the plan view of FIG. 7A, the mode dial 6 according to this embodiment has an appearance in which a bezel 63 is attached to the outside of the display board 61 having the laminated structure of the above-described embodiment. A knurled (non-slip) (not shown) is provided on the outer peripheral surface of the bezel 63.

  As shown in the sectional view of FIG. 7 (d), a light guide 62 made of milky white PC material is adhered to the back surface of the display board 61. The assembly of the display board 61 and the light guide 62 is as follows. It is rotatably attached to the camera housing 67 via the rotation shaft 64. Further, a collar 65 is interposed between the rotation shaft 64 and the camera housing 67 to make the mode dial 6 rotate smoothly. An LED 66 for illuminating the display board 61 is incorporated below the light guide 62.

  As shown in the enlarged view of FIG. 7E, the display board 61 has a structure in which a thin transparent film 20 is laminated on the surface of a transparent substrate 10. On the back surface of the film 20, a light-shielding positive display 20a (see black characters and pictograms in FIG. 7A) is printed. On the other hand, a metallic background decoration layer 21A is formed on the back surface of the substrate 10, and the light shielding layer 11 is printed under the background decoration layer 21A. On the light shielding layer 11, a negative display 11a corresponding to the contour shape of the positive display 20a is cut out and printed. Similar to the above embodiment, the negative display 11a has a slightly larger width dimension than the positive display 20a. Further, an illumination coloring layer 12 for coloring the illumination of the LED 66 is printed under the light shielding layer 11. The illumination coloring layer 12 colors the illumination of the LED 66 in an arbitrary color, for example, blue.

  In such a mode dial 6, when the LED 66 shown in FIG. 7A is not illuminated, the background of the display board 61 looks like a mirror-finished metallic tone by receiving light from the outside, and the character comprising the positive display 20 a. And the pictogram (for example, black) appears to have floated on the metallic background by the thickness of the substrate 10. Moreover, in this embodiment, since the background decoration layer 21A shown to the figure (e) has covered the translucent negative display 11a, when the LED66 is not illuminated, the outline shape of the negative display 11a can be seen. Absent.

  On the other hand, when the LED 66 shown in FIGS. 7B and 7C is illuminated, the illumination from the LED 66 passes through the illumination coloring layer 12, the negative display 11a, and the background decoration layer 21A, and is colored blue by the illumination coloring layer 12. The illuminated light illuminates the positive display 20a from behind. As a result, a planar character or pictograph consisting of the black positive display 20a emerges in the blue illumination that has passed through the negative display 11a, forming an individual three-dimensional display in the display board 6.

  According to the mode dial 6 of this embodiment, the planar positive display 20a can be given a thickness to give a three-dimensional effect and a floating feeling, and the entire appearance of the display board 6 can be illuminated and non-illuminated. And can be made different. As a result, it is possible to provide a mode dial 6 having a novel structure and appearance not found in conventional cameras.

[Seventh Embodiment]
Next, an embodiment of a dial of a speedometer provided with the display board of the present invention will be described with reference to FIGS.

  In FIG. 8A, the dial 7 of the speedometer according to the present embodiment is composed of a display board having the laminated structure of the above-described embodiment. As shown in the cross-sectional view of FIG. 5B, the dial 7 has a structure in which two transparent substrates 10 and 10 are stacked one above the other. The surface of the upper substrate 10 represents speed. A positive display 10a forming numbers is directly printed. In the present embodiment, the positive display 10a is white.

  On the other hand, a black light shielding layer 11 is printed on the surface of the lower substrate 10, and a decorative film 40 </ b> A is laminated on the light shielding layer 11. The decorative film 40A is formed with a fiber pattern of carbon fibers made of fine irregularities. As shown in FIG. 8B, the texture pattern of the decorative film 40A and the black light-shielding layer 11 are combined to form a black carbon fiber tone background.

  Moreover, negative display 40a, 11a corresponding to the positive display 10a is formed on the decorative film 40A and the light shielding layer 11, respectively. By forming the negative display 40a also on the decorative film 40A having translucency, the irregular reflection of the illumination due to the texture pattern is eliminated, and a reduction in the amount of illumination for illuminating the positive display 10a is prevented. Further, by eliminating irregular reflection of illumination due to the texture pattern, there is also an effect that the outline shape of illumination transmitted through the negative displays 40a and 11a is clearly defined.

  In such a dial 7, as shown in FIGS. 8 (a) and 8 (b), when the backlight (not shown) is not illuminated, a white positive display 10 a is displayed on a black carbon fiber tone background. It seems that the thickness of the substrate 10 is raised on the metallic background. In particular, on the black carbon fiber tone background, the white positive display 10a, which is the opposite color, stands out, and the visibility of the dial 7 is improved.

  On the other hand, when the backlight shown in FIGS. 8C and 8D is illuminated, the illumination is transmitted through the negative displays 11a and 40a and illuminates the positive display 20a from behind. As a result, a planar number consisting of the white positive display 20a emerges in the illumination that has passed through the negative displays 11a, 40a, forming an individual three-dimensional display in the dial 7. Here, as shown in FIG. 4D, when the positive display 10a is illuminated from behind in a dark place, the white positive display 10a becomes shaded by backlight and appears black. Therefore, on the dial 7 of the present embodiment, white planar numbers appear when the backlight is not illuminated, and a three-dimensional display consisting of black numbers and the thickness of the illuminated light appears when illuminated.

  According to the dial 7 of this embodiment, the planar positive display 10a can be provided with a thickness to give a three-dimensional effect and a floating feeling, and the entire appearance of the dial 7 can be illuminated and non-illuminated. And can be made different. As a result, it is possible to provide a dial 7 having a novel appearance that is not found in a conventional self-luminous dial.
